SMV1470-004LF Absolute Maximum Ratings Parameter Symbol Minimum Maximum Units Forward current IF 20 mA Power dissipation PD 250 mW Storage temperature TSTG 55 +150 C Operating temperature TA 55 +125 C Note: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
